DEPARTMENT OF MERIDIAN ASTROMETRY. 207 



STAFF. 



The Director spent a portion of the year exploring for a suitable 

 observing station in a region of the Southeastern United States 

 promising to offer favorable conditions for observing. He has also 

 devoted considerable attention to the future plans of the Department 

 and to special investigations. Dr. Sebastian Albrecht accompanied 

 the Director on his southern expedition, and has completed an in- 

 vestigation on personality in the estimation of tenths, besides continu- 

 ing his investigation of standards of wave-length. Mr. Sherwood B. 

 Grant resumed his duties after leaving the Navy and has been engaged 

 on various reductions. Mr. Heroy Jenkins continued the derivation 

 of systematic corrections to star catalogues. Mr. Harry Raymond 

 has been occupied with many departments of the work. Mr. Arthur J. 

 Roy has been mainly engaged in preparation of the San Luis catalogue 

 and was in charge of the Department during the absence of the 

 Director. Mr. William B. Varnum has continued to supervise the 

 reduction of the right-ascensions of the Albany observations and has 

 devoted considerable time to the investigation of an interesting 

 phenomenon developing from the study of clock-rates. Dr. Ralph E. 

 Wilson has been employed on a selection of comparison stars to be 

 used in connection with the photographic determination of star 

 positions. Miss Alice M. Fuller has continued as secretary of the 

 Department. 



The computing staff has been engaged on the multifarious opera- 

 tions involved in the reduction of the observations. It has consisted
